“…Mansour et al 123 numerically studied a mixed convection flow in a square lid-driven cavity partially heated from below and filled with different nanofluids to observe the effect of particles type and concentration on heat transfer. They reported that increase of solid volume fraction in the suspension raises the corresponding average Nusselt number.…”

Application of nanofluids in heat transfer enhancement is prospective. They are solid/liquid suspensions of higher thermal conductivity and viscosity compared to common working fluids. A number of studies have been performed on the effect of nanofluids in heat transfer to determine the enhancement of properties in addition to rearrangement of flow passage configurations. The principal objective of this study is to elaborate this research based on natural, forced, and the mixed heat transfer characteristics of nanofluids exclusively via convection for single-and two-phase mixture models. In this study, the convection heat transfer to nanofluids has been reviewed in various closed conduits both numerically and experimentally.

“…They showed that the Reynolds number has a significant effect on the streamlines and isotherms for different convective regimes. Mansour et al [10] analyzed the numerical simulation of mixed convection flow in a square lid-driven cavity partially heated from below using Cu-water, Ag-water, Al2O3-water and TiO2-water nanofluid. They showed that the increase in the solid volume fraction leads to a decrease in the activity of the fluid motion and the fluid temperature.…”

This investigation deals with the numerical simulation of entropy generation at mixed convection flow in a lid-driven saturated porous cavity submitted to a magnetic field. The magnetic field is applied in the direction that is normal to the cavity cross section. The governing equations, written in the Darcy-Brinkman-Forchheimer formulation, are solved using a numerical code based on the Control Volume Finite Element Method. The flow structure and heat transfer are presented in the form of streamlines, isotherms and average Nusselt number. The entropy generation was studied for various values of Darcy number (10 −3 ≤ Da ≤ 1) and for a range of Hartmann number (0 ≤ Ha ≤ 10 2 ). It was found that entropy generation is affected by the variations of the considered dimensionless physical parameters. Moreover, the form drag related to the Forchheimer effect remains significant until a critical Hartmann number value.

“…Authors reported that "It is clear from the results that the rate of thermal enhancement decreases with the increase of nanoparticles volume concentration". Mansour et al [8] were studied mixed convection flows in a square lid-driven cavity Experimental studies on convective heat transfer of Cu/Water,CuO/Water and Al 2 O 3 /Water nanofluids are reported by Zeinali et al [10,11]. The experimental set-up consisted of a one-meter annular tube, which was constructed of 6 mm diameter inner cupper tube 0.5 mm thick, and 32 mm diameter outer stainless steel tube.…”

ABSTRACT:In the present paper, the problem of transient laminar forced convection flow of nanofluids in horizontal square duct has been thoroughly investigated using a single phase approach. The water is adopted as base fluid ,while the(Al 2 O 3 ) and(CuO) are a solid nanoparticles. Computations are validated with experimental data available in the literature, good agreements are obtained. The results showed that Convective heat transfer coefficient for nanofluids is greater than that of the base liquid. Heat transfer enhancement increases with the particle volume concentration increase, but it is accompanied by increasing wall shear stress values. The isotherms are presented for various void fractions and Reynolds numbers. Also, the relation between the Nusselt number, and friction factor with Time are introduced for various Reynolds numbers and volume fraction of nanoparticles.
